Description

Polycomponent fiber product composite nano antibacterial agent, preparation method and application

Technical field

The present invention relates to a kind of nano antibacterial agent that is used for polycomponent fiber product, particularly a kind of methods for making and using same of nano antibacterial agent.

Background technology

Nanometer technology is a kind of novel research and development field that the structure of nanoscale material is tightened control.1 nanometer equals 1/1000000000th meter.Nano object is the intermediate of molecule and discrete material.

In the nanometer-scale scope, electronics owing to strong attraction, quantum effect, big area one volume when area-volumetric ratio show the characteristic of the unexistent machinery of discrete material, chemistry, photon, electric or magnetic.

Area effect and bulk effect are the imbodies of the peculiar property of nano material, and wherein area effect descends with the minimizing of nano material mean particle dia, and when increasing and the activated atom surface energy, the scale of surface atom will enlarge.The microcosmic that bulk effect refers to the nano-material surface atom and gross feature will experience by electron energy level separate, energy difference apart from enlarge, crystal pattern changes and surface atom density minimizing etc. causes irregular variation.

The applying nano technology can be made various innovative products with unique and good functional characteristic.Up to the present, the nanometer technology that can be used for industrialization is an applying nano materials, and for example nanometer powder, nanometer reagent, nanoelectronic pipe wait to produce and have product unique function nanometer product.

Natural fabric, artificial fibre and synthetic fiber performance are different, each tool pluses and minuses.Can learn from other's strong points to offset one's weaknesses by the compound various fibers of blended union, improve the wearability of lining greatly.From the garment material present situation, adopt the fabric of single raw material fewer and feweri, and get more and more by the fabric that multiple fiber combinations forms.More current popular blended union products have 2～3 kinds of fibers at least, contain 4～6 kinds of fibers at most, and mainly purposes and the class according to different product carries out proportioning, to reach the performance of improving product or to obtain special outward appearance.

Along with growth in the living standard, people have proposed further requirement to the function of taking fibre.Various functional fibers continue to bring out, antibiotic hygienic articles is accepted by people gradually.Being accompanied by huge commercial interest, development and application antibacterial fiber product becomes a trend of dress and personal adornment industry development.In recent years, antibiotic finish fibre market at home has finding also the time, but the product of nano antibacterial finishing seldom, and antibiotic finish does not then almost have to polycomponent fiber product.Therefore, the consumer extremely expects to develop a kind of antiseptic that is applicable to polycomponent fiber product, and is required to satisfy life.

Summary of the invention

The technical issues that need to address of the present invention are to disclose a kind of polycomponent fiber product nano antibacterial agent, preparation and application process thereof, to satisfy the needs of the parties concerned.

The component of nano antibacterial agent of the present invention and weight percent content are:

Inorganic nano antiseptic 5%～10%

Reactive organic antibacterial agent 15%～25%

Cationic antimicrobial is assisted agent 5%～10%

Distilled water surplus

Described inorganic nano antiseptic is selected from zeolite with carrying silver, titanium phosphate silver salt, titanium phosphate zinc salt, silver-colored ammonium complex salt, and a kind of or its mixture that carries in silver-colored silica gel, the silver soluble glass etc. is main active emulsion.

Described reactive organic antibacterial agent is selected from the reactant that triclabendazole, Miconazole, miconazole, isothiazolinone, Trimethoprim or pyrrole are foretold a kind of or its mixture in a kind of or its mixture in the acid amides and epoxychloropropane, ethylene glycol, propylene glycol, the glycerine.

Described cationic antimicrobial assists agent to be selected from two in fatty alcohol-polyoxyethylene ether (paregal O), alkylphenol polyoxyethylene (polyoxyethylene nonylphenol ether), dodecyl benzyl dimethyl ammonium chloride, dodecyl dimethyl benzyl ammonium bromide, Fixanol, the polyethylene glycol or three kind.

Composite nano antibacterial agent good stability of the present invention, itself is nontoxic, can not work the mischief to human body and environment, meets the national health ministerial standard.It is convenient to be used for the polycomponent fiber product arrangement, as long as fibre obtains 2%～5% antiseptic, the configuration aqueous solution is applied on the fabric, and oven dry just can make antibacterial fiber product then.

More existing inorganic silver is a nano antibacterial agent, and inorganic/organic nano composite antibacterial agent of being manufactured experimently among the present invention has good stability, and cost is low, and spectrum is antibiotic, and antibacterial effect is better, more lasting, and washability improves a lot.

Adopt the product of antiseptic arrangement of the present invention, adopted AATCC 100-1993 standard to detect by the parasite prevention and control of disease prevention and control center, Shanghai, the result shows, to 24h sterilizing rate＞99.99% of gold-coloured staphylococci, Escherichia coli, Candida albicans, the ability that has good restraining and kill each bacterioid, fungi.Show that arrangement back product has fairly obvious antibiotic, deodorizing, mildew-resistant effect.In addition, the clothing organization feel is unaffected, and antibacterial effect is lasting, washability is good, and after 100 washings, bacteriostasis rate still reaches more than 99%.

" fibre " that relates among the present invention can be fiber, wool top, yarn, woven, knitted fabric, nonwoven fabric.Can be cellulose fibre (comprising cotton, fiber crops, viscose glue, Mo Daier, day silk, copper amine fiber, acetate fibre, bamboo fibre etc.) in addition, and with one or more mixture of fibers in cellulose fibre 〉=60% and chemical fibre or the animal fiber.

Antibacterial fiber product among the present invention can be made interior outerwear trousers, sportswear, socks, carpet, bedding, automotive interior material, hospital gauze and the cloth that stretches tight, shoe-pad, seat cushion, aseptic operation clothes, healthcare givers's work clothes, johnny, aseptic mouth mask, hygienically packaged material, filtering material, diaper, sanltary towel, gloves, muffler, cap etc.
